read some of this stuff up, in a nutshell it's actually kinda simple to do if you already have everything needed to build the appropriate equipment

He speaks the truth, Hydrogen Fuel Cells are actually simple enough to be built in your home. However, most people can't acquire pure hydrogen (it's way to combustible), so you might have to get an electrolysis station set up.

Electricity is simply a method of putting energy into water to break the bonds between the hydrogen and oxygen. It's not like the electricity is stored in the hydrogen, it's just used to split the bonds. When you burn Hydrogen, you get energy, but it's in the form of heat.

At just over 3227 ºC the water molecule breaks down into elemental hydrogen and oxygen, and at a temperature of 1527 ºC water breaks down into a few flammable components such as H2, O2, H2O, O, H and OH. Hydrogen spontaneously ignites at 585°C.

so technically if a big ass *really big* asteroid happened to hit an ocean..

Whenever I read stuff on blogs about hydrogen fuel cells, everyone's like 'lol it's not environmentally friendly cause you need to use electricity to get hydrogen'. Could you use a hydrogen cell/s to do whatever you need to do to get hyrdrogen in a state to use it in fuel cells or would you put more in than you get out (I know this sounds unbeliveably ignorant)
